PURPOSE: Arrhythmias after an esophagectomy (most commonly atrial fibrillation) are a significant contributing factor to patient morbidity. However, the significance of an intraoperative arrhythmia is not completely understood. The aim of this retrospective study was to determine the occurrence and risk factors for developing intraoperative arrhythmias in patients undergoing an esophagectomy. MATERIALS AND METHODS: We reviewed the records of 427 patients who underwent a transthoracic esophagectomy between 2001 and 2005. Variables such as age, sex, hypertension, diabetes, cardiac disease, preoperative pulmonary function test (PFT) results, cancer level, combined radiochemotherapy, intrathoracic cavity adhesions and anastomosis site, hemoglobin, central venous pressure (CVP), fluid balance, serum potassium level, dose of vasopressors, temperature, and combined general and epidural anesthesia were analyzed as risk factors for the occurrence of an arrhythmia. We defined this arrhythmia as one not originating from the sinus node. RESULTES: The incidence of intraoperative arrhythmia in this subset of patients was 17.1%, with a 37.2% reoccurrence rate during the first three postoperative days. Univariate and multivariate analysis revealed the presence of heart disease, poor PFTs, cervical anastomosis, elevated CVP, and higher ephedrine doses to be independent predictors of the development of an intraoperative arrhythmia. CONCLUSION: The incidence of intraoperative arrhythmia during esophagectomy was 17.1% with a 37.2% of reoccurrence rate.

OBJECTIVEMucopolysaccharidosis(MPS) is a congenital hereditary disease. Only a few patients with this disease can be controlled by enzyme replacement therapy. Most of them are short of effective interference. To exploit the effect of treatment with allogenic hematopoietic stem cell transplantation, two children were treated with the transplantation.

METHODSThe two patients included a 23 month MPS-IH and an 18 month old MPS-VI at the time of transplantation. Busulfan of 20 mg/kg plus 200 mg of Cyclophosphamide were used as the conditioning regimen. Peripheral stem cells were collected from a 9/10 high resolution matched unrelated donor and a matched sibling carrier donor, respectively. The heart and lung were affected in the patient with MPS-IH. Medium obstructed pulmonary impairment was found by pulmonary function test at the time of transplantation. Medium mitral valve countercurrent and patent ductus arteriosis(PDA) were found by Doppla examination.

RESULTSThe number of hematopoietic stem cells was comparative between the two donors with total nucleated cells and CD34+ cells of 11 x 10(8)/kg and 17 x 10(8)/kg, and 7.6 x 10(6)/kg and 7.2x 10(6)/kg respectively. Neutrophil engrafted at day 11. The process of transplantation in the MPS-VI patient went smoothly with grade II graft versus host disease(GVHD) briefly and only 1 U RBC and 2 U platelet were transfused. For the MPS-IH patient, the process of transplantation was tough with platelet reaching to 20 x 10(9)/L till day 40 and 5 U RBC and 7 U platelet were transfused during transplantation. Grade III GVHD was resolved by steroid, mycophenolate mofetil (MMF) and CD25 antibody. Pneumonia recurred 3 times with 2 times rescued by trachea intubation and mechanical ventilation because of accompanying acute heart failure. At day 14 the lymphocytes in both patients were 100% from donors as evidenced by short tandem repeat-PCR(STR-PCR). MPS associated enzyme activity was increased to 70 nmol/h.mg and 66 nmol/h.mg at 3 month and still remained 50.9 nmol/h.mg and 44.5 nmol/h.mg at 2 years post transplantation. Till now the 2 patients have been followed up for 25 months and 28 months with good general condition. The cardiac and pulmonary functions have improved obviously in the MPS-IH patient. The cornea became clear in this patient.

CONCLUSIONAllogeneic hematopoietic stem cell transplantation is an effective measure to treat patient with MPS-IH and MPS-VI. Transplantation at earlier stage of age can decrease transplant related complications. It requires longer time follow up for observing the clinical effects for these patients.

OBJECTIVETo discuss the prevention and management of the neurological complications during treatment for severe scoliosis.

METHODSSeventy-one patients with the coronal Cobb angle more than 80 degrees underwent operation. The average coronal Cobb angle was 96.6 degrees (80 degrees - 135 degrees ), and 31 patients combined with kyphotic deformity with average sagittal Cobb angle 83.0 degrees (52 degrees - 145 degrees ). Fourteen patients were treated with posterior pedicle screw fixation alone, 21 combined with posterior wedge resection, 34 with staged operation, and 2 with combined anterior and posterior approach. Intraoperative somatosensory evoked potentials (SEP) monitoring and wake up test were used in 61 cases, and wake up test was used alone in 10 cases.

RESULTSThe average coronal curve correction was 59.2% (average 39.6 degrees ) and sagittal curve correction was 61.6% (average 31.9 degrees ). Thirty-nine patients were followed up with average 51 months (5 - 81 months). Among them, 33 patients achieved solid spinal fusion and the rate of correction loss was 2.1%. Two patients underwent reoperation because of the breakages of the internal fixation. Among 8 patients with neurological dysfunction pre-operatively, 3 patients obtained complete recovery, 1 patient incomplete recovery, and the rest had not recovered because of post-poliomyelitis syndrome. Four of 5 patients developed neurological dysfunction post-operatively obtained complete recovery and 1 partial recovery.

CONCLUSIONSHalo-pelvic distraction and apical vertebra osteotomy are useful for increasing the correction rate and decreasing the neurological dysfunction. Intraoperative SEP monitoring combined with wake up test can call attention to early nerve injury. Early using of glucocorticoids and dehydration therapy promptly post-operatively is benefit to prevent neurological complications.
